Application filed October 20, 1920. Serial No. 418,250.

To all whom it may concern.

Be it known that I, AmNzo A. WARNER, a citizen ofthe United States,residing at New Britain,-county of Hartford, State of Connecticut, haveinvented a certain new and useful Improvement in Vacuum-Cleaner Nozzles,of which the following is a full, clear, and exact description.

- My invention relates to nozzles for vacu- 1 um cleaners and has forits object to provide the mouth of a nozzle with agitators which willstir the surface of the rug or carpet and hold the lips of the mouth ofthe nozzle'slightly away from the surface being cleaned. It also has forits object to provide means for stirring the dust and threads on acarpet so that they will be more effectively sucked up without beingcollected mechanically by the. nozzle when in use. It further has forits object to provide means for securing an even barometric pressureat'all parts of the mouth. 1

The following is a description of an embodiment of my invention,reference being 95 had to the accompanying drawings, in

which, I

Fig. 1 is a front view of a nozzle embodying my invention;

Fig. 2 is an inverted plan view of the mouth of the nozzle, the bodyportion of the nozzle being broken away; and,

Fig. 3 is an end view of the nozzle, show-;

ing part in elevation and part. in section,

on the line 3-3, Fig. 1.

Referring more particularly to the drawings, l is a nozzle for a vacuumcleaner. 2, 2 are series of agitators which perferably project slightlyinto the slot 3 of the nozzle. These agitators have rear extensionswhich 40 project downward from the surface of the lips 4 of the mouth,as shown at 5, so as to separatethe portions between the agitators 2, 2slightly from the floor or carpet and provide spaces which permit theair to draw through into the nozzle. The corners of the month areprovided with raised portions 6 Whose lower surfaces are flush with thelower surfaces of the agitators and these raised portions 6 areseparated by grooved spaces-7, whichpermit air to be drawn in. endwiseof the nozzle so that dust can be drawn in from corners and from pointsad-' jacent to the'baseboards of a room. The mouth just inside thelips'is' narrowed at its center, as shown at 8, 8 and widens graduallytowards its ends so as to equalize the suction at all points. Theagitators extend upward as at 9, 9 so as to substantially merge with theinner surface of the nozzle. This does awa with horizontal surfaces onthe upper si es of the agitators, on which dust would be deposited fromeddy currents within the nozzle, which dust would be liable to bedislodged and scattered on the car et when the cleaner was set down. Ita so prevents the agitators from catching on any looped warp or woof ofthe carpet during the reciprocating movement of the cleaner and therebyinjuring the carpet. It also prevents loosethreads from becoming caughton the agitators so as to be held against the suction action. Thespacing function of the agitators makes it unnecessary to rovide meansfor ad'usting the distance 0 the nozzle from the cor, as heretofore hasbeen done by rather complicated devices. In order to get the best effectI prefer to have the agitators extend be end the inner edges of thelips, as shown. The. nozzle is provided with the usual rubber buffer 10.As will beevident to those skilled in the art, my invention permitsofvarious modifications without departing from the spirit thereof or thescope of the appended claim.

What I claim is: A vacuum cleaner nozzle having oppositely, dis osedagitators formed integral with'the ips ofthemouth of the nozzle, saidagitators on each lip being spaced apart and extending downwardly fromsaid lips so as to form a plurality of spaces between the lips andfloor, and having the'inner end portions of their sides taperinginwardly and projecting slightly inwardly beyond the 95 lips of thenozzle.
